Last week, I was at a restaurant with a group of friends. The bill came and this is what was
said…
“I’m not good at math, you figure
it out.”
Out to lunch…

Innumeracy21% of Americans possess numeracy skills at the lowest level . . . [which] means that
people cannot . . . work out the change from $2 when buying
goods worth $1.58.

Welcome BackAccording to the
Common Core, What is MOST IMPORTANT at your grade level?
Answer by placing one sticker on the chart.

The Three Shifts in Mathematics
Focus Coherence Rigor
Authors of the Common Core Math
Standards have emphasized 3 shifts
from old state standards
(like the NCSCOS)
![Page 20: Standards for Mathematical Practice 1. Make sense of complex problems and persevere in solving them. 2. Reason abstractly and quantitatively 3. Construct.](https://reader035.fdocuments.in/reader035/viewer/2022062504/5a4d1b927f8b9ab0599c19b3/html5/thumbnails/20.jpg)
Shift One: Focus strongly where the Standards focus
Significantly narrow the scope of content and deepen how time and energy is spent in the math classroom
Focus deeply only on what is emphasized in the standards, so that students gain strong foundations
![Page 21: Standards for Mathematical Practice 1. Make sense of complex problems and persevere in solving them. 2. Reason abstractly and quantitatively 3. Construct.](https://reader035.fdocuments.in/reader035/viewer/2022062504/5a4d1b927f8b9ab0599c19b3/html5/thumbnails/21.jpg)
Why Focus?
The U.S. curriculum before the Common Core was known as ‘a mile wide and an inch deep.’What did this look like in the NCSCOS?
Focus is necessary in order to achieve the rigor set forth in the standards
![Page 22: Standards for Mathematical Practice 1. Make sense of complex problems and persevere in solving them. 2. Reason abstractly and quantitatively 3. Construct.](https://reader035.fdocuments.in/reader035/viewer/2022062504/5a4d1b927f8b9ab0599c19b3/html5/thumbnails/22.jpg)

Teach Less, Learn More!

How will teaching fewer “topics” in each grade change your planning?

Content Emphasis
Designed to help teachers focus on what is most important at each grade level.
Focus
![Page 25: Standards for Mathematical Practice 1. Make sense of complex problems and persevere in solving them. 2. Reason abstractly and quantitatively 3. Construct.](https://reader035.fdocuments.in/reader035/viewer/2022062504/5a4d1b927f8b9ab0599c19b3/html5/thumbnails/25.jpg)
Content Emphases by Cluster
Not all of the content in a given grade is emphasized equally in the standards.
Some clusters require greater emphasis based on the depth of the ideas, the time that they take to master, and/or their importance to future mathematics or the demands of college and career readiness.
An intense focus on the most critical material at each grade allows depth in learning, which is carried out through the Standards for Mathematical Practice.
Focus does not mean neglecting certain standards. Neglecting material will leave gaps in student skill and understanding and may leave students unprepared for the challenges of a later grade.

Coherence Wrap-up When teaching the Common Core, teachers should: Carefully connect the learning within and across
grades so that students can build new understanding onto foundations built in previous years.
Begin to count on solid conceptual understanding of core content and build on it. Each standard is not a new set of events, but an extension of previous learning.

Shift Three: Rigor
The CCSSM require a balance of: Solid conceptual understanding Procedural skill and fluency Application of skills in problem solving situations
This requires balanced intensity in time, activities, and resources in pursuit of all three

shifts? (Focus, Coherence, Rigor) How could Mr. D extend this lesson to develop
students thinking around adding and subtracting fractions or decomposition of fractions?

Practice 5Use Appropriate Tools Strategically…
On the count of 3, you have 30 seconds to find as many colored tiles as possible. When the time is up, please bring them back to your group.
Complete the tally chart with your groups tiles. Then construct a bar graph with your data. Combine group data to make a class bar graph. Range, Median, Mode What conclusions can you draw?? How might the data relate to
animals in the wild? How does hiding the tiles around the room affect the lesson?

What would that look like…
With our students?

Step 1: Introduce/Review Standards for Mathematical Practice # 4 and #5
Date:
Briefly describe how you will introduce/review Standards for Mathematical Practice # 4 and #5
Step 2: Apply Standards for Mathematical Practice # 4 and #5 to a math lesson.Select a lesson that provides students the opportunity to choose appropriate tools strategically and model with mathematics.
Briefly describe lesson chosen:
Toward the end of the lesson, ask students to illustrate how they used mathematical practice #4 OR #5 in their work today.
Step 3: Bring illustrations to math planning.As a team, choose 2 illustrations (one that shows a solid understanding and one that shows minimal understanding). Send illustrations in to Amy and Marilyn (use envelope provided).
